If you were wondering why ArenaNet seemed so heavy handed when it banned some 3,000 accounts for exploiting an in-game vendor, here's your answer: the Guild Wars 2 in-game Trading Post. Thousands of players being able to buy really, really, low and then sell really, really, high (whether it be the actual items or the components you get from breaking items down) probably mucks up the game's economy...

The Trading Post went live yesterday after a brand new update. Basically it allows you to auction off your little baubles in the game for in-game currency.

"We've been expanding the Trading Post's capacity to handle the huge volume of requested trades," read a statement on the Guild Wars 2 wiki last night. "After our test yesterday, we've been working to resolve some issues reported by players. We expect to have the Trading Post online for all players this evening (edit: after tonight's software update)."

Besides the turning on the Trading Post for all Guild Wars 2 players, the recent update fixes character storyline bugs, a handful of exploits, and increases the game server's capacity to handle new players entering the game.
